For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Driven by intelligent and automated high-tech, the smart home industry has entered a period of rapid development. The smart home industry is facing new challenges and opportunities in the transformation of technology, market and industry.

[0037] According to the function, the smart home can be divided into eight modules: entertainment system, security system, control system, lighting system, kitchen and bathroom appliance system, network and communication system, health care system, and indoor environment system. The eight modules work together to realize the whole house intelligence.

[0038] When plugging in and out of a plug-in circuit breaker and a cabinet, if the circuit breaker is pulled out when it is in the closed state, it is easy to cause safety hazards and have a certain impact on the stability of the circuit breaker. In some implementations, the circuit breaker cannot be pulled out when it is closed, and the circuit breaker with an unlocking function cannot be assembled with accessories.

[0039] To solve the above problems, one aspect of an embodiment of the present application provides a circuit breaker, including a housing, an operating mechanism 200 and a locking device, and also includes a locking device cooperating with the locking device to lock and / or release the circuit breaker.

[0040] The locking device is linked to the locking device, which can unlock the circuit breaker and open the operating mechanism at the same time, preventing the circuit breaker from being pulled out in the closed state, avoiding the user from operating with power on, ensuring personal safety, and improving the safety and stability of the circuit breaker. Through reasonable space layout, the circuit breaker can be compactly set, which is conducive to the scene requirements of miniaturization of circuit breakers.

[0041] Furthermore, the locking device is slidably mounted on the housing 100, and the locking device is rotatably mounted on the housing 100, and the locking device is located at one side of the locking device.

[0042] The locking device includes an unlocking member 101 and a connecting member 102 that cooperates with the unlocking member 101 , and the connecting member 102 is located on one side of the unlocking member 101 .

[0043] The circuit breaker includes at least one of the following:

[0044] The locking device includes a locking member 103 and a driving member 104 that cooperates with the locking member 103, and the driving member 104 is located on one side of the locking member 103;

[0045] The operating mechanism includes a limiting member 105 which is linked to the locking device.

[0046] Please refer to Figure 1 and Figure 2As shown, the unlocking member 101 and the connecting member 102 are rotatably arranged on the housing 100 of the circuit breaker, and the locking member 103 is slidably arranged in the housing 100. The rotation of the unlocking member 101 drives the connecting member 102 to rotate, thereby driving the locking member 103 to translate, so that the locking member 103 extends out or retracts into the housing 100.

[0047] The unlocking member 101 drives the locking member 103 to translate to extend or retract into the housing 100, so that the circuit breaker is engaged with the cabinet when the locking member 103 is extended, and is inserted into or pulled out of the cabinet when the locking member 103 is retracted; the locking member 103 is linked with the operating mechanism 200 through the driving member 104, so that the operating mechanism 200 is opened when the circuit breaker is pulled out of the cabinet.

[0048] The circuit breaker further comprises an operating mechanism, and the locking device is linked with the operating mechanism to open the circuit breaker and / or release the circuit breaker.

[0049] The driving member 104 is also used to connect with the limiting member 105 of the operating mechanism 200, and the driving member 104 drives the operating mechanism 200 to operate through the limiting member 105. The limiting member 105 is located below the lock 201 of the operating mechanism 200, and the driving member 104 drives the operating mechanism 200 to operate through the limiting member 105, so that the operating mechanism 200 is opened when the circuit breaker is pulled out of the cabinet.

[0050] The unlocking member 101 is rotatably set on the shell 100. By manipulating the unlocking member 101, the locking member 103 can be driven to translate, so that the locking member 103 extends out of the shell 100 or retracts into the shell 100. It can be seen that in this application, the rotational movement of the unlocking member 101 is converted into the translational movement of the locking member 103.

[0051] In addition, a first reset member (not shown in the figure) is also provided on the unlocking member 101. The first reset member is arranged along the rotation direction of the unlocking member 101 and is generally a reset spring. The reset spring is arranged in the groove of the unlocking member 101, one end of which is connected to the shell 100 and the other end is connected to the unlocking member 101. When the unlocking member 101 rotates, the reset spring is driven to rotate; when the unlocking member 101 needs to be reset, the energy accumulated in the reset spring can drive the unlocking member 101 to rotate and reset.

[0052] And / or, it also includes a second reset member 1031 that is linked to the locking member 103 to reset the locking member 103.

[0053] When the circuit breaker is inserted into the cabinet, the unlocking member 101 is pressed, and the unlocking member 101 drives the locking member 103 to retract into the housing 100 to unlock the circuit breaker, and the circuit breaker can be inserted into the cabinet. After releasing the unlocking member 101, the unlocking member 101 rotates and resets under the drive of the first reset member, and the locking member 103 extends out of the housing 100 under the action of the second reset member 1031 to achieve the snap connection with the cabinet, so that the circuit breaker is snap-connected and locked with the cabinet; when the circuit breaker is pulled out of the cabinet, the unlocking member 101 is pressed, and the unlocking member 101 drives the locking member 103 to retract into the housing 100 to unlock the circuit breaker, and the circuit breaker can be pulled out of the cabinet.

[0054] On this basis, in order to prevent the circuit breaker from being pulled out in the closed state, the operating mechanism is opened 200 times while the circuit breaker is unlocked to prevent adverse effects on personal safety.

[0055] The driving member 104 is also connected to the limiting member 105 of the operating mechanism 200. When the circuit breaker is in the closed state, the unlocking member 101 is pressed, and the unlocking member 101 drives the locking member 103 to retract into the housing 100 to unlock the circuit breaker. At this time, the circuit breaker can be pulled out of the cabinet; at the same time, when the driving member 104 is actuated, the limiting member 105 is driven to rotate, thereby driving the operating mechanism 200 to open. In this way, when the circuit breaker is pulled out, the operating mechanism 200 is opened while the circuit breaker is unlocked, thereby avoiding the situation where the circuit breaker is pulled out of the cabinet in the closed state.

[0056] Furthermore, the limiter 105 is located below the lock buckle 201 of the operating mechanism 200, and the limiter 105 drives the lock buckle 201 to rotate to realize the opening of the operating mechanism 200; at the same time, a reset force is provided for the lock buckle 201, and because the limiter 105 is located below the lock buckle 201, the limiter 105 can be linked with the accessories, and the limiter 105 circuit breaker can be driven while the accessories of the circuit breaker are assembled. On the other hand, the limiter 105 and the third push rod 104b are arranged below the lock buckle 201, which can make full use of the space below the operating mechanism 200, realize a compact structural arrangement, and facilitate the needs of miniaturization scenarios.

[0057] It should be noted that the limiter 105 is used to realize the assembly of accessories and the resetting of the lock 201. Through the cooperation between the circuit breaker and the operating mechanism 200, the circuit breaker is unlocked, the accessories are assembled, and the lock 201 is reset.

[0058] Therefore, the circuit breaker provided in the embodiment of the present application drives the locking member 103 to translate by rotating the unlocking member 101, so that the locking member 103 can extend or retract into the housing 100; when the locking member 103 extends out of the housing 100, the circuit breaker and the cabinet are locked by a card connection, so as to prevent the circuit breaker from accidentally falling out of the installation position and improve the stability of the circuit breaker; when the locking member 103 is retracted into the housing 100, the circuit breaker can be inserted into or pulled out of the cabinet. At the same time, the driving member 104 is also connected to the operating mechanism 200, and through the translation movement of the locking member 103, the driving member 104 drives the limiting member 105 to rotate, thereby realizing the opening of the operating mechanism 200, so that the circuit breaker is unlocked and the operating mechanism 200 is opened, so as to prevent the circuit breaker from being pulled out in the closed state, avoid the user's live operation, ensure personal safety, and improve the safety and stability of the circuit breaker.

[0059] Furthermore, the limit member 105 and the third push rod 104b are located below the lock 201 of the operating mechanism 200, and can be linked with the accessories through the limit member 105, so that the limit member 105 circuit breaker can be driven while the accessories of the circuit breaker are assembled and the lock is reset; it can also make full use of the space below the operating mechanism 200, make a reasonable spatial layout, and realize the compact setting of the circuit breaker, which is conducive to the scenario requirements of miniaturization of the circuit breaker.

[0060] The connecting member 102 is located between the unlocking member 101 and the locking member 103. Figure 5 As shown, the connecting member 102 is rotatably connected to the shell 100 through the mounting hole 102b, and a strip hole 102a is formed at the end of the connecting member 102. One end of the unlocking member 101 extends into the strip hole 102a to be rotatably connected to the connecting member 102; and the other end of the connecting member 102 is provided with a first push rod 102c extending toward the locking member 103, and the locking member 103 has an extension rod 103A that abuts against the first push rod 102c. When the unlocking member 101 rotates to drive the connecting member 102 to rotate, the first push rod 102c on the connecting member 102 pushes the first abutting surface 103a of the extension rod 103A of the locking member 103 to make the locking member 103 translate.

[0061] like Figure 4 As shown, a boss 1030 is formed at one end of the locking member 103, and a limiting groove 100a matching the boss 1030 is formed on the housing 100. When the locking member 103 translates, the boss 1030 of the locking member 103 extends out of or retracts into the housing 100 through the notch of the limiting groove 100a, thereby realizing the snap-fit ​​locking of the circuit breaker and the cabinet, or the insertion and removal of the circuit breaker from the cabinet.

[0062] At the same time, the limiting groove 100a can also prevent the locking member 103 from retracting into the housing 100 when the circuit breaker and the cabinet are locked, causing the circuit breaker to accidentally fall out of the installation position, thereby improving the stability of the circuit breaker.

[0063] like Figure 6 As shown, the locking member 103 is also connected to a second reset member 1031, which is a reset spring and is arranged along the translation direction of the locking member 103 to drive the locking member 103 to translate and reset. The locking member 103 can translate in the direction of retracting into the housing 100 through the pushing action of the first push rod 102c of the connecting member 102; when the locking member 103 is locked into the housing 100, the second reset member 1031 is compressed; when the locking member 103 needs to be extended out of the housing 100, the second reset member 1031 pushes the locking member 103 to extend out of the housing 100 for translation and reset.

[0064] A slide groove 100b is provided in the shell 100, and the second reset member 1031 and / or the locking member 103 are provided in the slide groove 100b, one end of the second reset member 1031 is connected to the slide groove 100b; and / or one end of the second reset member 1031 is connected to the locking member 103.

[0065] For example, one end of the second restoring member 1031 is connected to the slide groove 100 b , and the other end is connected to the locking member 103 .

[0066] A slide groove 100b is formed on the shell 100, and the notch of the slide groove 100b corresponds to the notch of the limit groove 100a on the shell 100; the locking member 103 is movably set in the slide groove 100b, and the left end of the locking member 103 is connected to the second reset member 1031, and part of the second reset member 1031 is located in the installation groove 103c of the locking member 103; the locking member 103 can slide along the slide groove 100b, and extend and / or retract into the shell 100 through the notch of the limit groove 100a; when the locking member 103 is translated and retracted along the slide groove 100b, the second reset member 1031 is compressed, and the energy accumulated in the second reset member 1031 can make the locking member 103 translate along the slide groove 100b and extend out of the shell 100.

[0067] The locking member 103 is also provided with a limiting boss 103 d that cooperates with the limiting groove 100 a . The limiting boss 103 d abuts against the inner wall of the housing 100 at the limiting groove 100 a to limit the locking member 103 from extending out of the housing 100 .

[0068] like Figure 6 As shown, the locking member 103 forms a limiting boss 103d near the boss 1030, the limiting boss 103d is located above the slide slot 100b, and the lower part of the locking member 103 located at the limiting boss 103d is located in the slide slot 100b, so that the locking member 103 can translate in the slide slot 100b without being restricted by the limiting boss 103d. The limiting boss 103d is blocked by the limiting groove 100a, and the limiting boss 103d and the inner wall of the housing 100 at the limiting groove 100a are abutted to limit the locking member 103 from extending out of the housing 100.

[0069] When the locking piece 103 moves toward the direction of extending out of the limiting groove 100a, part of the locking piece 103 extends out of the shell 100. Due to the restriction of the limiting boss 103d, the locking piece 103 cannot continue to translate toward the outside of the shell 100, thereby limiting the locking piece 103 from extending out of the shell 100.

[0070] like Figure 3 As shown, the driving member 104 is connected to the limiting member 105 , and the locking member 103 linearly drives the driving member 104 to rotate, so as to drive the operating mechanism 200 to open the gate through the limiting member 105 .

[0071] The driving member 104 is located between the operating mechanism 200 and the locking member 103. When the locking member 103 moves in translation, it drives the driving member 104 to rotate, and the driving member 104 drives the limiting member 105 to rotate, thereby driving the lock buckle 201 to rotate to realize the opening of the operating mechanism 200.

[0072] The driving member 104 is rotatably disposed in the housing 100, and the driving member 104 is provided with at least one of the following structures for opening the circuit breaker:

[0073] A second push rod 104a abutting against the locking member 103;

[0074] The third push rod 104 b abuts against the limiting member 105 .

[0075] The second push rod 104a of the driving member 104 abuts against the second abutting surface 103b on the extension rod 103A of the locking member 103. When the locking member 103 is retracted into the housing 100 to unlock the circuit breaker, the circuit breaker can be plugged in and out. At the same time, when the locking member 103 is retracted into the housing 100, the extension rod 103A of the locking member 103 drives the second push rod 104a to rotate the driving member 104, and the driving member 104 drives the limiting member 105 to rotate through its third push rod 104b, thereby realizing the opening of the operating mechanism 200.

[0076] The contact point between the third push rod 104b of the driving member 104 and the limit member 105 is located at the bottom end of the limit member 105. The limit member 105 and the third push rod 104b are located below the lock 201. The limit member 105 and the accessories are linked to drive the limit member 105 circuit breaker while realizing the accessory assembly and lock resetting of the circuit breaker, and can make full use of the space below the operating mechanism 200, so that the circuit breaker is compact, which is conducive to the miniaturization of the circuit breaker.

[0077] And / or, a third reset member 1041 is provided on the driving member 104. The third reset member 1041 is generally also a reset spring. The reset spring is provided on the driving member 104, one end of which is connected to the shell 100 and the other end is connected to the driving member 104. When the driving member 104 rotates, the third reset member 1041 is driven to rotate, and the third reset member 1041 is reversed to reset the driving member 104.

[0078] In summary, a slide groove 100b is provided in the housing 100 of the circuit breaker, and the locking member 103 is movably arranged in the slide groove 100b of the housing 100, and can extend out of the housing 100 to engage with the cabinet to lock the circuit breaker; the unlocking member 101 is rotatably connected to the housing 100, the unlocking member 101 is drivingly connected to the connecting member 102, the connecting member 102 is drivingly connected to the locking member 103, the locking member 103 is drivingly connected to the driving member 104, the driving member 104 is located between the operating mechanism 200 and the locking member 103, and the driving member 104 is linked with the operating mechanism 200 through the limiting member 105; the unlocking member 101 is rotated, and the force on the unlocking member 101 is transmitted to the locking member 103 through the connecting member 102, so that the locking member 103 is retracted into the housing 100 to unlock the circuit breaker, and the circuit breaker can be plugged and unplugged;
